TouchDesigner Tutorial | Twisting Sphere with Changing Colors

[@Delta_li_gifs]

Thank you so much for the overview in the beginning! Ithelps so much. I was having trouble giving color to SOPS but now I understand.

[@deadmusik9969]

I really enjoyed this tut, the music is a nice complement

[@acrylicode]

Thank you so much! Glad you enjoyed it!

@@acrylicode Just got to trying it and @5:59 I typed in the expression [ op('null1').numPoints/op('shuffle1').numSample ], and I get an error saying td.attribuite error no numSample . Any help please :D

[@acrylicode]

@@deadmusik9969 it is op('shuffle1').numSamples with an 's' at the end :) You can also refer to the Touch Designer Documentation for expressions docs.derivative.ca/CHOP_Class check the members list.

​@@acrylicode Thank you ill have to look up this stuff sorry, I was not in the right box for expression. Thank you for the tutorial :D

[@brvoigt]

Nice tutorial and technique! Small note, “TouchDesigner” is spelt as one word.

[@AndyDuplain]

Great stuff! Many thanks!

[@acrylicode]

Happy you liked it, you're welcome!

So helpful, thanks a lot!

You're welcome ;)

Creo que te amo! eres tan dulce y generosa! 😉

is there a way to change the grid color? mine is showing up as a darkish gray and it's always visible. i'm trying to get it to be almost black so it blends with the background and creates that floating effect i see here.

[@hanaowens793]

at 3:18 when i assign the different translation on x,y,z to p(0), (1), (2), it does not change into the different particle system like it does on yours. it just stays the same?

[@acrylicode]

Did you set the TranslateOP to null1?

[@hanaowens793]

@@acrylicode thank you, I realised that I was setting up in the geo 2 instance and not geo 1. Thank you for your quick reply!

[@rebeccacoratella2765]

How can I make the colour change as a gradient like you did? I would like to make the colours audio-reactive

[@mauricioaudiovisual]

3:39 could you copy this code here? there are characters that I can't write :( . the expression is not in the comments. sorry

[@acrylicode]

op('constant1')['res'] 💙

[@joanavalente944]

love the tutorial.. how did you change de color so smoothly? :D

[@acrylicode]

I used a custom component ;)

[@Dantheon]

Hi, thank you for this video. I have a problem with the floor of my render being grey instead of black like yours. Any help would be greatly appreaciated

[@mauriciogonzalezgomez6902]

did you ever find a way to fix this? i'm having the same problem...

[@kainerda2088]

Hmm, understanding of data manipulation with CHOPs seems to be a fundamental problem for me. I can somehow follow this action with the shuffle, stretch, numPoints, numSamples and so on in the tutorial, but I have no real idea what exactly happens there. You make it sound like the most obvious thing in the world, but I would never have thought of doing that by myself. :|

[@notarabbit1752]

So the idea is that the stretch needs some notion of being scaled so that it matches the number of samples at null1 and we are giving it the correct ratio. Like if null1 had twice as many samples, we would tell it to scale 2/1 or double it. So "null1samples"/"shufflesamples" gives the correct scaling. Its actually a little applied algebra because you can look at it as: null1samples = scale*shufflesamples therefore: scale = null1samples/shufflesamples but I agree that its not obvious!

[@treyluciano5139]

When I put the code in and fix it like she did it still doesn’t work for me. Can anyone help?

[@acrylicode]

Can you please be more specific on what it is that is not working? Are you having an error? Which is the error message? Which part of the video is not working?

[@maximrivers]

are you looking for this one? op('null1').numPoints/op('shuffle1').numSamples
